Floristic units and their predictors unveiled in part of the Atlantic Forest hotspot: implications for conservation planning Anais da ABC (AABC)
SAITER,FELIPE Z.; EISENLOHR,PEDRO V.; FRANÇA,GLAUCO S.; STEHMANN,JOÃO R.; THOMAS,WILLIAM W.; OLIVEIRA-FILHO,ARY T. DE.
ABSTRACT We submitted tree species occurrence and geoclimatic data from 59 sites in a river basin in the Atlantic Forest of southeastern Brazil to ordination, ANOVA, and cluster analyses with the goals of investigating the causes of phytogeographic patterns and determining whether the six recognized subregions represent distinct floristic units. We found that both climate and space were significantly (p ≤ 0.05) important in the explanation of phytogeographic patterns. Floristic variations follow thermal gradients linked to elevation in both coastal and inland subregions. A gradient of precipitation seasonality was found to be related to floristic variation up to 100 km inland from the ocean. The temperature of the warmest quarter and the precipitation...
